Being a noob, I have some questions regarding if I should SLAM or not. Yesterday and I did a OCLT because I found two places of random yellow stains in spa that would not brush off but would lighten with the application of a puck, the OCLT passed with losing 1.0 ppm of FC and O CC.
However, last night I noticed this stain at the bottom of my pool water (not the best picture) but it's yellow in nature and like the others won't brush off and the automatic vacuum cleaner won't pick it up. So another OCLT was performed, same results. FC loss of 1.0 ppm and 0 CC.
My water is clear. So I'm wondering is this algae? Should I go forward with the SLAM process?
Testing times for both OCLT and FC levels (were identical):
2100: 6.5 FC/ 0 CC
0645: 5.5 FC/ 0 CC
My CYA is 40. Question about that too. I live in El Paso, and other threads I've read have mentioned to raise CYA levels to about 50-60 to combat the heat and sun exposure? Is that something I should do now?
Thanks.
